springBoot中starter

springBoot项目中引入starter

项目引入xxljob，仅需要导入对应的starter包，即可进行快速开发

<dependency><groupId>com.ydl</groupId><artifactId>xxl-job-spring-boot-starter</artifactId><version>0.0.1-SNAPSHOT</version>
</dependency>

xxl-job-spring-boot-starter

目录结构：

pom.xml中仅导入对应的xxl-job-spring-boot-autoconfiguration依赖

 xxlJobAutoConfiguration为配置类，springBoot启动时会加重

xxlJobProperties

pom.xml导入相关的jar包

spring.factories文件（spring启动的时候会加载此文件中的配置类）

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.ydl.xxljobspringbootautoconfiguration.XxlJobAutoConfiguration

另外这个spring.factories文件还可配置监听类

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.alibaba.boot.dubbo.autoconfigure.DubboAutoConfigurationorg.springframework.context.ApplicationListener=\
com.alibaba.boot.dubbo.context.event.OverrideDubboConfigApplicationListener,\
com.alibaba.boot.dubbo.context.event.WelcomeLogoApplicationListener,\
com.alibaba.boot.dubbo.context.event.AwaitingNonWebApplicationListener

public class AwaitingNonWebApplicationListener implements ApplicationListener<ApplicationReadyEvent> {@Order //最低优先级确保最后执行
public class OverrideDubboConfigApplicationListener implements ApplicationListener<ApplicationEnvironmentPreparedEvent> {@Order(LoggingApplicationListener.DEFAULT_ORDER + 1)
public class WelcomeLogoApplicationListener implements ApplicationListener<ApplicationEnvironmentPreparedEvent> {
